The scf_entry_reset() function resets a transaction entry, disassociating it from any transaction
it is a part of (invalidating the transaction in the process), and
disassociating any values that were added to it.

The scf_entry_destroy_children() function destroys all values associated with the transaction entry. The
entry itself is not destroyed.

Return Values

Upon successful completion, scf_entry_create() returns a new scf_transaction_entry_t. Otherwise, it returns NULL.

Upon successful completion, scf_entry_handle() returns the handle associated with the transaction entry.
Otherwise, it returns NULL.
